CUDA Kernel Benchmarking Package

This package provides Python API to CUDA Kernel Benchmarking Library NVBench.

Building

Build NVBench project

cd nvbench/python
cmake -B nvbench_build --preset nvbench-ci -S $(pwd)/.. -DCMAKE_CUDA_COMPILER=/usr/local/cuda/bin/nvcc -DNVBench_ENABLE_EXAMPLES=OFF -DCMAKE_INSTALL_PREFIX=$(pwd)/nvbench_install
cmake --build nvbench_build/ --config Release --target install

nvbench_DIR=$(pwd)/nvbench_install/lib/cmake CUDACXX=/usr/local/cuda/bin/nvcc pip install -e .

Verify that package works

export PYTHONPATH=$(pwd):${PYTHONPATH}
python test/run_1.py
